Application Notes
- Current Feedback Amplifiers: Review, Stability Analysis, and ApplicationsPDF, 53 Кб, Файл опубликован: 20 ноя 2000
The majority of op amp circuits are closed-loop feedback systems that implement classical control theory analysis. Analog designers are comfortable with Voltage FeedBack (VFB) op amps in a closed-loop system and are familiar with the ideal op amp approximations feedback permit. This application bulletin will demonstrate how CFB op amps can be analyzed in a similar fashion. Once the closed-loop sim - Stabilizing Current-Feedback Op Amps While Optimizing Circuit PerformancePDF, 280 Кб, Файл опубликован: 28 апр 2004
Optimizing a circuit design with a current-feedback (CFB) op amp is a relatively straightforward task, once one understands how CFB op amps achieve stability. This application note explains a 2nd-order CFB model so that any designer can better understand the flexibility of the CFB op amp. This report also discusses stability analysis, the effects of parasitic components due to PCBs, optimization - Active filters using current-feedback amplifiersPDF, 227 Кб, Файл опубликован: 25 фев 2005

- Noise Analysis for High Speed Op Amps (Rev. A)PDF, 256 Кб, Версия: A, Файл опубликован: 17 янв 2005
As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu - Tuning in AmplifiersPDF, 44 Кб, Файл опубликован: 2 окт 2000
Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket? Oscil - Single-Supply Operation of Operational AmplifiersPDF, 77 Кб, Файл опубликован: 2 окт 2000
Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation. - Op Amp Performance AnalysisPDF, 76 Кб, Файл опубликован: 2 окт 2000
This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
